[boost] Release branch regression testing failures

Stale tests have been cleared, and there is a fresh release branch regression test report up at: http://beta.boost.org/development/tests/release/developer/summary.html Libraries reporting errors on more than one platform are: bimap - all platforms failing build - all non-Linux platforms failing math - all platforms failing numeric/interval - two platforms failing optional - two platforms failing python - Linux platforms failing spirit - all platforms failing type_traits - all platforms failing units - two platforms failing I'd appreciate it if the developers involved would clear these tests in the next few days. Thanks, --Beman
